I never understood the logic of the no camera policy. Cameras have gotten so small these days, it would be very easy to sneak one most anywhere - unless you are in the few locations that basically do a strip search of workers (saw something like this about the diamond industry - probably Discovery channel). There are also USB drives, phones with USB ports, e-mail and all kinds of other ways to steal data instead of taking pictures of it.

In my facility I did have to sign something stating I would not take personal photographs in the facility, but they don't have a problem with my blackberry. I did even use it to e-mail a picture to a supplier concerning a problem of a completly non-classified component.
